Joyce ----- I think physan can combat some fungus on the outside ..... but not on the inside, as I don't think it's a systematic fungicide. Systematic fungicides will be products like thiomyl and phosacid products (eg. monterey garden phos, agri-fos).
Thank you, SouthPark...this yellowing is now happening to my plant's "sister", growing in the original bark mix, as well as 2 recently repotted Angcm Lemforde White Beauty. I am really at a loss...
I am beginning to suspect the smoke from our wildfires, as the air has been rated Hazardous (over 500) for several days. No other plants seem affected...yet...
Angraecums yellow rapidly if you don't water enough or if they move from warm & humid environments to cooler & more arid environments. I think those are more likely your problem.

I've experienced what Ray describes a number of times when repotting into different media or mounting, and all are recovering well and putting out new roots now.
Hi Steve, the Angraecums that I repotted are growing lots of new green root tips, and one Lemforde White Beauty is just now showing a flower spike (!) so I am thinking that maybe this was indeed a new-medium issue.
